BACKGROUND

Field of the Invention

This patent document generally relates to a protective sleeve for substantially enclosing a portable electronic device, and more particularly to a protective sleeve for cleaning a touchscreen of the portable electronic device, and various methods for its use.

Related Art

Protective sleeves and cases for portable electronic devices such as laptops, tablets, and smartphones are numerous and vary widely in shape, size, material and function. Most sleeves are designed at least to protect the portable electronic device from external damage, whether it is scratches, hard impacts such as drops, or just general contact, as such, protective sleeves are limited primarily to simply protecting the portable electronic device when it is not in use.

Many portable electronic devices, specifically touchscreen devices can become dirty when they are being used as a result of a user's fingers touching the screen or the screen coming in contact with dirt or other particles. Conventional techniques to clean a touchscreen involve wiping the screen clean with a cloth, such as a microfiber or cleaning cloth, which attracts the oils, dirt and other particles which are deposited on the touchscreen during use; however, these techniques require carrying around a separate cloth to clean the touchscreen. Furthermore, a flat, one-sided cloth may be somewhat difficult to hold and apply to the touchscreen.

SUMMARY

Embodiments described herein provide for a protective cleaning sleeve which substantially encloses a portable electronic device and which is configured with a narrowed stretchable cuff/opening made from a material that stretches and/or contacts. In certain embodiments, surfaces of the sleeve can be constructed such that it cleans the portable electronic device when the device is being inserted into and removed from the sleeve. The cuff/opening can be configured with a customized width or diameter narrower than a width of the portable electronic device.

According to one aspect, a protective cleaning sleeve for a portable electronic device includes: an elastic protective pouch with a first width; and an elastic opening with a second width on one end the protective pouch, wherein the second width is smaller than the first width, and wherein the elastic opening includes a material which cleans a surface of the portable electronic device.

The sleeve itself may be made from one material on an outside surface that allows the outside surface to be highly ornamental while a material on an inside surface may be selected such that it can be used to clean the portable electronic device by manual application of the interior surface to the display screen. The material on the outside surface can be more or less durable than the material on the inside surface.

The sleeve can be designed to be turned inside out and used as a cleaning mitt where a user may place a hand inside the sleeve, so that it is easier to apply the cleaning surface to the portable electronic device.

The sleeve may also be configured with one or more accessories, for example an elastic loop for retaining a cable, charging plug, a tie-on loop, and an external pocket for a pen or a stylus.

DETAILED DESCRIPTION

Certain embodiments disclosed herein provide for a protective cleaning sleeve that substantially encloses a portable electronic device (with or without a third party case/keyboard/stand) and that includes a narrowed stretchable cuff/opening. In some embodiments, the stretchable cuff/opening of the disclosed protective cleaning sleeve is configured with a customized width or diameter narrower than a width of the portable electronic device so that the sleeve substantially closes around the portable electronic device and provides sufficient friction to prevent the device from slipping back out of the sleeve. In this way, no closing mechanism, such as a synch of tie is required. This lowers cost, makes the sleeve easier to produce, and easier to use.

In one embodiment, a protective cleaning sleeve for a portable electronic device includes: an elastic protective pouch with a first width; and an elastic opening with a second width on one end of the protective pouch, wherein the second width is smaller than the first width. The sleeve itself can be made from one material on an outside surface that is more durable while a material on an inside surface can be more protective of the portable electronic device. The interior surface material can also be a cleaning material that operates to clean the device by manual application of the interior surface to the display screen. The sleeve can also be designed to be turned inside out and used as a cleaning mitt where a user may place a hand inside the sleeve, so that it is easier to apply the cleaning surface to the portable electronic device. In some embodiments, the sleeve can also be configured with one or more accessories, for example an elastic loop for retaining a cable, charging plug, a tie-on loop, and an external pocket for a pen, stylus, or other accessory or device.

In another aspect, a protective cleaning sleeve for a portable electronic device is disclosed. This protective cleaning sleeve includes a protective pouch having a first width and a stretchable cuff attached to an open end of the protective pouch at a first end of the stretchable cuff and having an elastic opening at a second end of the stretchable cuff, wherein the elastic opening has a second width smaller than the first width. Moreover, the stretchable cuff includes a material having cleaning properties, and hence the stretchable cuff can be used to clean a surface of the device. The cuff can also be configured such that it cleans a surface of the portable electronic device when the portable electronic device is being inserted into or removed from the protective pouch through the elastic opening

In a further aspect, a device for storing and cleaning a portable electronic device is disclosed. This device includes a pouch comprising a first panel and a second panel, wherein the pouch has an opening and a first width, which is substantially equal to the width of the portable electronic device. The device also includes a stretchable cuff comprising a first half cuff and a second half cuff and attached to the opening of the pouch, wherein the stretchable cuff has an elastic opening that has a second width substantially smaller than the width of the portable electronic device. Furthermore, the first panel of the pouch and the first half cuff form a first side of the pouch and the second panel of the pouch and the second half cuff form a second side of the pouch. Moreover, the first half cuff is made from a first fabric having cleaning properties so that the inner surface of the first half cuff can clean a surface of the portable electronic device.

FIG. 1 illustrates an exemplary protective cleaning sleeve 100 in accordance with an example embodiment described herein. As can be seen in FIG. 1, sleeve 100 includes a pouch 102 which can be used to substantially enclose a portable electronic device such as a tablet or smartphone, and a cuff 104 having an opening 110 where the portable electronic device can be inserted and removed from pouch 102. Note that a width 112 of opening 110 is narrower than a width 106 of pouch 102.

Pouch 102 can primarily comprise two panels, i.e., a front panel and a back panel which may be sewn together on three sides of the two panels, i.e., the left, the right and the bottom sides as shown in FIG. 1. In other embodiments, pouch 102 is made from a single panel that is folded into a front panel and a back panel and that is then sewn together along two sides to form pouch 102. Pouch 102 may be configured with width 106 and a height 108 to comfortably fit a target portable electronic device, such as a tablet or a smartphone. Dimensions of some exemplary pouches are described below with regard to FIG. 2.

Pouch 102 can be formed from a single layer of fabric, which is soft, elastic and provides cleaning properties when the fabric makes contact with the surface of the portable electronic device. In some embodiments, a fabric such as French terry (also referred to as “terry cloth”) can be used to make a single layer pouch, as this fabric has a smooth surface (for the outside of the pouch) and a nubby/terry surface on the inside. Other fabrics that can be used for the single layer design can include micro-suede, terry velour, bamboo, rayon jersey or any other fabric that is stretchable and useful for cleaning. In one embodiment, the fabric contains approximately 2% or more of stretchable material such as Lycra™, Elastane™, or other types of spandex. In another embodiment, the fabric contains between 0.5%-50% of stretchable material such as Lycra™, Elastane™, or other types of spandex. In yet another embodiment, the fabric contains between 0.01%-99% of stretchable material such as Lycra™, Elastane™, or other types of spandex. Note that the fabric can have either a 2-way (i.e., one-dimensional) or a 4-way (i.e., two-directional) stretch properties.

In some embodiments, the pouch can include at least two layers of materials: an outer layer that can provide a more durable surface to protect the portable electronic device inside sleeve 100 and to protect the sleeve from wear and tear, and an inner layer comprising a stretchable fabric that can provide a cleaning function. In such embodiments, the outer layer can also be formed with a material such as a fabric capable of being decorated or embellished in order to personalize the sleeve for the user. In some embodiments, the outer layer of pouch 102 can even include leather. Note that the outer layer material does not have to be stretchable.

The inner layer material can include terry cloth, microfiber, micro-suede, terry velour, bamboo, rayon jersey or any other fabric that is useful for cleaning (including both overall surface cleaning and spot-cleaning) the surfaces of portable electronic devices, and particularly for the glass surfaces and other touchscreen surfaces. In one embodiment, each of the outer layer and inner layer contains approximately at least 2% or more of stretchable material such as Lycra™, Elastane™, or other types of spandex. In another embodiment, each of the outer layer and inner layer contain approximately 0.5%-50% of stretchable material such as Lycra™, Elastane™, or other types of spandex. In yet another embodiment, each of the outer layer and inner layer contain approximately 0.01%-99% of stretchable material such as Lycra™, Elastane™, or other types of spandex.

Note that pouch 102 can be made from a fabric that is stretchable but does not contain spandex. This stretch property can be achieved by cutting on the bias of the fabric, which is when the fabric's warp and weft threads are at an angle, such as 45 degrees to the fabric's major seam lines. Typically, woven fabric is more elastic as well as more fluid in the bias direction, compared to the straight and cross grains. Using a fabric that is cut on the bias for the pouch material allows the fabric to provide a necessary amount of stretch without having to contain stretchable material such as Lycra™, Elastane™, or other types of spandex.

In some embodiments, pouch 102 is made of different materials on different portions of pouch 102. For example, one portion of pouch 102 can be made from a stretchable material, while the other portion can be made from a material with little or no stretch ability. Furthermore, the stretchable portion of pouch 102 can be formed from either a single layer of material or two layers of materials including an inner layer and an outer layer. If a single layer of material is used for the stretchable portion of pouch 102, the single layer of material can be a soft, elastic material having cleaning properties thereby providing a cleaning function when the material is making contact with the surface of the portable electronic device. If two layers of materials are used for the stretchable portion of pouch 102, the outer layer can be formed from a material to provide a more durable surface, while the inner layer can be formed to include a material which is soft and elastic having cleaning properties thereby providing a cleaning function when the material is making contact with the surface of the portable electronic device.

In one embodiment, the stretchable portion of pouch 102 should be at least half of the total surface area of pouch 102. For example, in a two-panel configuration of pouch 102, the stretchable portion can be one of the two panels. On the other hand, the non-stretchable portion of pouch 102 can be formed from a rigid material, a semi-rigid material such as grass cloth or other semi-rigid materials. Moreover, the non-stretchable portion of pouch 102 can be decorated or embellished for personalizing the sleeve for the user.

Note that, when the inner layer of the two-layer construction of pouch 102 is configured with cleaning properties, a user can manipulate the pouch portion of protective cleaning sleeve 100 against the portable electronic device when the device is substantially enclosed by the sleeve 100 to clean and spot-clean the touchscreen and other surfaces of the portable electronic device. For the embodiments of the single-layer construction of pouch 102, if the single-layer material is configured with cleaning properties, the above-described cleaning technique for an enclosed portable electronic device can be similarly applied to clean the portable electronic device.

In another embodiment, the sleeve 100 can be turned inside out and used as a cleaning cloth mitt on the portable electronic device, where the user places a hand inside the inside-out pouch 102. In this embodiment, pouch 102 can be configured with dimensions to substantially cover a user's hand or fingers (depending on the overall size of the sleeve) and therefore make it easier to manually clean a surface of the portable electronic device than just using a flat, square cleaning cloth.

In the embodiment shown in FIG. 1, sleeve 100 also includes a cuff 104 on one end of sleeve 100. As can be seen in FIG. 1, cuff 104 is attached to the top edge of pouch 102 on one side and has an opening 110 on the other side for a portable electronic device to be inserted into and removed from pouch 102. In one embodiment, cuff 104 is formed from an elastic material, such as Lycra™ or Elastane™, and is configured with width 112 at opening 110 that is narrower than width 106 of pouch 102. As can be seen in FIG. 1, width 112 of cuff 104 is made sufficiently narrow to retain the portable electronic device securely within sleeve 100. Moreover, width 112 of cuff 104 also allows the inner surface of cuff 104 to make frictional contact with the surface of the portable electronic device when the portable electronic device is being inserted into or removed from pouch 102. Width 112 can be determined based on the specific dimensions of the portable electronic device to be enclosed to ensure that cuff 104 can expand to accommodate the width of the portable electronic device.

In certain embodiments, width 112 of cuff 104 can be configured to allow the material of cuff 104 to provide sufficient frictional contact with the surface of the portable electronic device to at least partially remove any smudges, fingerprints, dirt or other particles on the portable electronic device.

In some embodiments, the height 114 of cuff 104 should have a minimum dimension to provide a significant amount of contact with the portable electronic device when the portable electronic device passes through opening 110 in either direction.

In some embodiments, cuff 104 is formed from a single layer of fabric that is soft, stretchable and has cleaning properties to provide a cleaning function when the fabric is making contact with the surface of the portable electronic device. The single layer of fabric can include terry cloth, microfiber, micro-suede, terry velour, bamboo, rayon jersey or any other fabric which is stretchable and useful for cleaning (including both overall cleaning and spot-cleaning) the surfaces of portable electronic devices. In other embodiments, cuff 104 can include two layers of materials: an outer layer that is made of a stretchable fabric and that can have cleaning properties, and an inner layer that is made of a stretchable fabric that has cleaning properties to provide a cleaning function when the fabric is making contact with the surface of the portable electronic device. The inner layer fabric can include terry cloth, microfiber, micro-suede, terry velour, bamboo, rayon jersey or any other fabric, which is useful for cleaning (including both overall cleaning and spot-cleaning) the surfaces of portable electronic devices. As mentioned above, cuff 104 can be made of a fabric that is cut on the bias to allow the fabric to provide sufficient stretch without having to contain stretchable material such as Lycra™, Elastane™, or other types of spandex.

In some embodiments, one portion of cuff 104 can be made by a stretchable fabric having cleaning properties while the other portion of cuff 104 can be made by a stretchable fabric without cleaning properties. Furthermore, the portion of cuff 104 having the cleaning properties can be formed from either a single layer of material or two layers of materials including an inner layer and an outer layer. If a single layer of material is used for the portion of cuff 104 having the cleaning properties, the single layer of material provides a cleaning function when the material is making contact with the surface of the portable electronic device. If two layers of materials are used for the portion of cuff 104 having the cleaning properties, the outer layer may be formed from a stretchable material without cleaning properties, while the inner layer may be formed from a stretchable material having cleaning properties to provide a cleaning function when the material is making contact with the surface of the portable electronic device. The portion of cuff 104 having the cleaning properties should be at least half of the total surface area of cuff 104.

In some embodiments, a portion of the outside surface, an entirely side of the outside surface, or the entire outside surface of pouch 102 can be made of one or more materials having cleaning properties. In some other embodiments, a portion of the outside surface, an entirely side of the outside surface, or the entire outside surface of cuff 104 can be made of one or more materials having cleaning properties. In yet some other embodiments, a portion of the outside surface, an entirely side of the outside surface, or the entire outside surface of sleeve 100 can be made of one or materials having cleaning properties. Hence, sleeve 200 can have cleaning materials on both the interior surface and the exterior surface. In some embodiments, sleeve 100 is made entirely with bamboo fabric which is considered a cleaning material. In some other embodiments, sleeve 100 includes half microfiber interior and half microsuede exterior, and as a result, sleeve 100 can be used for cleaning with either the interior or the exterior. Sleeve 100 can also be made entirely with a cleaning material on the interior using microsuede or microfiber without stretch in the cleaning material, wherein the cleaning material is cut on a bias.

In one embodiment, width 112 of cuff 104 at opening 110 can be determined based on a ratio of width 106 of pouch 102 to width 112 of cuff 104. This ratio allows the sleeve 100 to be customized for any sized portable electronic device to be placed inside the sleeve by determining an ideal width 112 for cuff 104 after width 106 of pouch 102 is determined for a given sized portable electronic device. In this manner, desirable dimensions of the sleeve 100 can be achieved to ensure that the device does not fall out of sleeve 100. In one example, sleeve 100 has a width ratio range of approximately 15:11 (or 1.36) to approximately 13:9 (or 1.44). In this example, an exemplary sleeve having a ratio of 15:11 and a pouch width of 7.5 inches will have a cuff width of about 5.5 inches, while an exemplary sleeve having a ratio of 13:9 and a pouch width of 6.5 inches will have a cuff width of about 4.5 inches. In some embodiments, the ratio of width 106 of pouch 102 to width 112 of cuff 104 may be determined based on the material or materials that cuff 104 and pouch 102 are made of. For example, if cuff 104 is formed from a more stretchable material, the width ratio can be made to be at the higher end of the range of possible ratios, for example, close to 1.44. In some embodiments, width 112 of cuff 104 at opening 110 can range from 3″-8″, and an actual width value within this range can be determined based on the size of pouch 102, amount of stretch in the fabric of cuff 104, and composition of materials in pouch 102 and cuff 104.

Table 1 presents a list of fabric materials, which may be used to make the protective cleaning sleeve 100 and exemplary compositions in accordance with some embodiments, described herein. As can be seen from the Table 1 below, each of the listed fabric contains a particular percentage of spandex thereby making them stretchable to various extents. Note that each of the fabric listed below may be used for both pouch 102 and cuff 104 of sleeve 100.

FIG. 2 illustrates various exemplary sizes of the disclosed protective cleaning sleeve 100 in accordance with some embodiments described herein. More specifically, FIG. 2 shows a smaller sleeve 202 (A) designed for a 7-inch portable electronic device such as a 7-inch tablet and a larger sleeve 204 (B) designed for a 10-inch portable electronic device such as a 10-inch tablet. As can be seen in FIG. 2, for the smaller sleeve 202, the pouch 206 of sleeve 202 has a width of approximately 6⅝ inches, while cuff 208 of sleeve 202 has a width at the opening of approximately 4¾ inches. For the larger sleeve 204, the pouch 210 has a width of approximately 7½ inches, while the cuff 212 of sleeve 204 has a width at the opening of approximately 5⅞ inches. In each of the exemplary sleeves above, the cuff portion of the sleeves should have a sufficient height to provide a significant amount of contact with the portable electronic device when the portable electronic device passes through the associated openings. In the embodiments shown in FIG. 2, the heights of cuff 208 and cuff 212 are both approximately 1⅜ inches; however, other heights greater or smaller than 1⅜ inches can be used in other embodiments.

FIG. 3 shows a schematic of protective cleaning sleeve 100 that is cut open along seams to demonstrate various exemplary material configurations for protective cleaning sleeve 100 in accordance with some embodiments described herein. As can be seen in FIG. 3, sleeve 102 has been separated into two halves, i.e., a left half sleeve including left half pouch 102-1 plus left half cuff 102-1, and right half pouch 102-2 and right half cuff 104-2. Because each of pouch 102 and cuff 104 can be configured in a two-layer configuration, the following discussion of the material composition refers to either a single layer configuration of protective cleaning sleeve 100 or the interior/inner layer material composition of a two-layer configuration of protective cleaning sleeve 100.

In some embodiments, entire cuff 104 (i.e., both left half cuff 104-1 and right half cuff 104-2) is made from a fabric having desired cleaning properties, such as microfiber. In these embodiments, pouch 102 can be made from a stretchable fabric other than microfiber, such as bamboo. In some embodiments, only half of sleeve 100 is made from a fabric having desired cleaning properties, such as microfiber, wherein the half of sleeve 100 with cleaning properties can be either left half cuff 104-1 plus left half pouch 102-1, or right half cuff 104-2 plus right half pouch 102-2. In these embodiments, the other half of sleeve 100 can be made from a stretchable fabric other than microfiber, such as bamboo. In some other embodiments, only half of cuff 104 (i.e., either left half cuff 104-1 or right half cuff 104-2) is made from a fabric having desired cleaning properties, such as microfiber. In these embodiments, the rest of sleeve 100 other than the half of cuff 104 having cleaning properties can be made from a stretchable fabric other than microfiber, such as bamboo. In still other embodiments, up to ¾ but no more than ¾ of entire sleeve 100 is made from a fabric having desired cleaning properties, such as microfiber, while the remaining portion of no less than ¼ of sleeve 100 is made from a stretchable fabric other than microfiber, such as bamboo. And in still other embodiments just pouch 102-1 or 102-2 can be made of fabric having the desired cleaning properties.

Table 2 presents a list of exemplary material compositions and dimensions of exemplary protective cleaning sleeves for small-size tablet devices in accordance with some embodiments described herein. As can be seen from the Table 2 below, the first exemplary sleeve is made entirely from bamboo fabric, the second exemplary sleeve is made from bamboo in the entire pouch portion and half of the cuff portion, while other half of the cuff portion is made from microfiber. In the third exemplary sleeve half of the pouch portion and half of the cuff portion are made from bamboo fiber, while other half of the pouch portion and the other half of cuff portion are made from microfiber.

In one embodiment, inserting the portable electronic device into the disclosed protective cleaning sleeve, such as sleeve 100, requires expanding the width of the elastic opening of the cuff as the portable electronic device passes through the opening and makes contact with an inner surface of cuff with at least one surface of the portable electronic device. Hence, when the inner surface of the cuff contacting the surface of the portable electronic device has clean properties, the insertion operation can also clean the surface of the portable electronic device. When the portable electronic device is fully inserted into the pouch of the sleeve, the opening of the cuff reverts to its un-expanded configuration and substantially encloses the portable electronic device within the sleeve to substantially secure the portable electronic device within the sleeve. Once the portable electronic device is enclosed within the sleeve, a user may further manipulate the surface of the pouch to make contact with an inner surface of the pouch and a surface of the portable electronic device making contact with that inner surface to further clean the surface of the portable electronic device.

Similarly, when removing the portable electronic device from the sleeve, the elastic opening of the cuff is expanded and the portable electronic device is pulled through the expanded opening while the inner surface of the cuff makes contact with a surface of the portable electronic device to clean the surface of the portable electronic device throughout the remove process. Once the portable electronic device has been pulled completely through the opening of the cuff, the opening reverts to its un-expanded configuration. Because the disclosed sleeve allows the screen of a portable electronic device to be cleaned each time when the device is being inserted into or removed from the sleeve, the disclosed sleeve facilitates simplifying the device screen cleaning operation, increasing the cleaning frequencies, maintaining cleaning efficacy, and as a result, minimizing or eliminating damages to the screen and protecting the device from moisture both when the device is stored inside the protective cleaning sleeve and being used outside the protective cleaning sleeve.

In some embodiments, the disclosed protective cleaning sleeve can be turned inside out and used like a glove or mitt where a user can place a hand inside the turned sleeve, so that an inner surface having cleaning properties of the sleeve can be applied to the screen of the portable electronic device to either wipe-clean the entire screen surface or spot-clean sections of the screen.
